The verdict: unrealized gains and losses on assets like Bitcoin do not count toward CAMT calculations for large corporations. In plain English, companies will not be taxed on Bitcoin price changes unless they actually sell.
Why It Matters for Corporate Bitcoin Holders
For firms with big Bitcoin positions, this news could not have come at a better time. It removes a cloud of uncertainty that had been hanging over corporate treasuries and signals a friendlier stance from regulators toward long‑term digital asset strategies.
The CAMT, introduced in 2022, requires large corporations with over $1 billion in yearly profits to pay at least a 15 percent tax on their adjusted financial income. Until this week, it was unclear whether unrealized Bitcoin gains would be included. That created a major headache for companies like MicroStrategy, which holds around $16 billion in Bitcoin as of September. If CAMT applied to those unrealized gains, the firm could have faced steep tax bills just for holding.
I don’t think you realize how significant this is.
This IRS guidance (issued Sept 30, 2025) clarifies that unrealized gains/losses on digital assets like Bitcoin are excluded from Corporate Alternative Minimum Tax (CAMT) calculations for large corps.

Instead, the new IRS guidance confirms that MicroStrategy’s “buy and hold” approach does not trigger CAMT taxes. The company will only pay tax if it sells Bitcoin for a profit. This keeps its long‑term accumulation strategy intact and may embolden other firms to follow its lead. In the same way that Tesla sparked interest by adding Bitcoin to its balance sheet in 2021, MicroStrategy’s success under the new tax rules could inspire the next wave of corporate adoption.
As a result of Treasury and IRS interim guidance issued yesterday, Strategy does not expect to be subject to the Corporate Alternate Minimum Tax (CAMT) due to unrealized gains on its bitcoin holdings. $MSTRhttps://t.co/Qlo9rHPR5J

A Nudge for Wider Treasury Adoption
The timing is notable. Corporate interest in Bitcoin has been climbing again in 2025. According to CoinMetrics, institutional wallets have seen a steady increase in inflows this year, with over $2 billion in Bitcoin moving into large addresses tied to funds and corporations since June. Companies considering a Bitcoin allocation now have one less obstacle to worry about.
Bitcoin Treasury Companies are down ~30-90% from 52wk highs.

The tax relief also puts Bitcoin on a more level playing field with traditional assets like gold or stocks, which are not taxed until sold. This consistency reduces friction and simplifies planning for finance teams that might have hesitated to add Bitcoin due to unclear accounting or tax treatment.
